When the review ended, the no-goal call was upheld due to a lack of indisputable evidence. For it to be a goal, there needed to be white between the puck and the goal line. And sure, the replay angles weren't great, but the league has the ability to zoom in. Nonetheless, it relies heavily on overhead camera angles rather than available goal-line technology.

From the NHL: Video review determined that there were no definitive replays which showed that the puck completely crossed the Washington goal line.

That would be where the space between the puck and the goal line was visible. The NBC broadcast would later show that same zoomed-in look, calling it indisputable. The NHL just didn't see it that way because the overhead camera angle was obstructed by traffic around the net.

Somehow, the replay center couldn't act on that look, and it certainly cost the Penguins as the Capitals drew even in the series.

Even with the overhead angle obstructed, the goal-line technology utilized in international soccer and tennis would help the NHL avoid these controversial no-goal decisions. Penguins players were adamant that it was a goal. Via USA TODAY Sports:

"It's 100 percent a goal," Penguins coach Mike Sullivan said. "When you blow it up, you can see the white. It's behind the post. That's how we saw it. We respectfully disagree with the league. But that's not anything we can control."

Washington would add an empty-net goal to lock up the 4-1 win. The teams head to Pittsburgh for Game 3 on Tuesday.
